Battery Voltage Check
After switch on, if LCD displays low battery voltage icon
“
“
，
which
indicates that battery voltage is low, and please replace the battery in time.
3. Ground voltage measurement
Please make sure testing wire plug has been totally inserted into testers
corresponding interface and it may cause measurement value error for
incomplete insert or poor contact.
The tester cannot be used for commercial power supply voltage
measurement. For special situation that needs to measure, it can only
use V, E interface to connect for measurement. It is not allowed to
measure commercial power voltage in the case of short circuit of H, S
interface. Otherwise, measuring voltage in the earthing circuit of cutout
switch may cause cutout switch start.
On measuring earthing voltage, please do not impose
over 600V
voltage
on measurement connectors.
When measuring ground voltage, do not touch exposed conductors to
avoid electric shock.
After the auxiliary grounding rod and test line are connected, switch the
function button U to the voltage level, the LCD displays the voltage to ground,
and the measured voltage to ground cannot exceed 600V.
In general, for measuring earthing voltage, it is only to connect the
testing wires
corresponding to
V
,
E
interface. As shown:
